I hope this has not been asked before, I have been searching the internet for the past few days for answers to this problem and haven't found anything yet. Randomly in the past few days Windows 7 explorer/my documents folder/anywhere in my computer locks up and stops responding when I try to use my keyboard. No matter what I try to do, renaming documents, using ctrl-c, pressing shift, using any key on the keyboard, it locks up. I have tried running windows updates, running virus scanning, spyware scanning....nothing will work. Is anyone else having this problem and been able to solve it?
